Description

Technical Field

[0001] This utility model belongs to the field of vehicle rearview mirror front half shell processing technology, specifically involving injection molds for producing vehicle rearview mirror front half shells in pairs. Background Technology

[0002] Automotive rearview mirror manufacturing refers to the process of producing automotive rearview mirrors from raw materials through a series of technological steps. This process typically includes multiple stages such as mold design, injection molding, surface treatment, assembly, and quality inspection. First, a mold is created according to the design requirements, and then plastic or metal materials are injected into the mold using an injection molding machine. After molding, the rearview mirror requires surface treatment, such as electroplating or painting, to improve its durability and aesthetics. Next, different components are assembled, including the lens, housing, and adjustment mechanism. Finally, a rigorous quality inspection process ensures the functionality and safety of the rearview mirror. Automotive rearview mirror manufacturing not only requires high precision and efficiency but also must comply with relevant safety standards and environmental protection requirements.

[0003] Currently, existing injection molds for producing the front half of vehicle rearview mirrors in pairs present challenges during use. When processing the front half of the rearview mirror for different vehicle models or when the mold wears out and needs to be disassembled and replaced, the bolt-fixed installation of most injection molds makes disassembly and replacement cumbersome and hinders quick replacement, greatly reducing processing efficiency. Therefore, we propose an injection mold for producing the front half of vehicle rearview mirrors in pairs. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for producing the front half shell of a vehicle rearview mirror in pairs, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for producing the front half shell of a vehicle rearview mirror in pairs, comprising a lower mold, an mounting groove, and gears. The lower mold has a mounting groove at its top, and both ends of the inner walls on both sides of the mounting groove have snap-fit ​​grooves. A core block is provided inside the mounting groove at the top of the lower mold. Sliding blocks are provided on both sides of the core block. A straight rod and a Z-shaped rod are respectively connected to one end of the snap-fit ​​blocks on both sides of the core block. Rectangular grooves are provided at the bottom ends of the other two sides of the core block. An L-shaped lever is slidably arranged inside the rectangular groove. One end of the L-shaped lever is fixedly connected to the straight rod. Gears are installed on both sides of the core block via a provided rotating shaft. The straight rod and the Z-shaped rod extend to the bottom and top of the gear respectively and mesh with the gear through the provided tooth grooves.

[0006] Preferably, an upper mold is provided directly above the top of the lower mold, and an installation groove is also provided at the bottom of the upper mold corresponding to the core block. A cavity block is provided inside the installation groove at the bottom of the upper mold, and the top two sides of the cavity block have the same structure as the bottom two sides of the core block.

[0007] Preferably, a torsion spring is fitted around one end of the rotating shaft, and the two ends of the torsion spring are fixedly connected to the gear and the inner wall of the core block or cavity block, respectively.

[0008] Preferably, guide rods are fixedly welded to the bottom of the core block and the top of the cavity block, and guide grooves are provided on the bottom surface and top wall of the mounting groove, with the guide rods inserted into the guide grooves.

[0009] Preferably, guide posts are provided around the top of the lower mold, and the guide posts are fixedly installed around the top of the lower mold by welding.

[0010] Preferably, the bottom of the upper mold is provided with guide holes around its perimeter, and the position and diameter of the guide holes are the same as those of the guide posts.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By adopting a snap-fit ​​method, the L-shaped lever pulls the corresponding snap-fit ​​block to retract, which in turn drives the gear to rotate. The gear then drives the Z-shaped lever to retract synchronously, causing the corresponding snap-fit ​​block to retract into the core block or cavity block. This achieves the snap-fit ​​installation and release function. In conjunction with a torsion spring, the reset effect is improved, and the stability of the snap-fit ​​block in the extended state is enhanced. This design greatly improves the convenience of disassembly and assembly.

[0012] 2. By using the guide groove set in the mounting slot, together with the guide rods set at the bottom of the core block and the top of the cavity block, the core block and cavity block are guided and limited, thereby improving the stability of the core block and cavity block after installation, avoiding displacement, and preventing deviations during mold closing, which could affect the processing hardness.

[0016] Please see Figure 1-3 This utility model provides a technical solution for injection molding of the front half shell of a vehicle rearview mirror produced in pairs: it includes a lower mold 1, a mounting groove 7, and a gear 15. The top of the lower mold 1 is provided with a mounting groove 7. Both ends of the inner walls on both sides of the mounting groove 7 are provided with snap-fit ​​grooves 8. The mounting groove 7 at the top of the lower mold 1 is provided with a core block 5. The outer sides of the core block 5 are slidably provided with snap-fit ​​blocks 13. One end of the snap-fit ​​blocks 13 on both sides of the core block 5 is respectively connected to a straight rod 12 and a Z-shaped rod 18. The bottom ends of the other two sides of the core block 5 are provided with rectangular grooves 10. The rectangular grooves 10 are slidably provided with L-shaped levers 11. One end of the L-shaped levers 11 is fixedly connected to the straight rod 12. The inner sides of the core block 5 are provided with gears 15 through a rotating shaft 16. The straight rod 12 and the Z-shaped rod 18 extend to the bottom and top of the gear 15 respectively and are connected to the gear 15 through the toothed grooves 14.

[0017] Specifically, an upper mold 2 is provided directly above the top of the lower mold 1. An installation groove 7 is also provided at the bottom of the upper mold 2 corresponding to the core block 5. A cavity block 6 is provided inside the installation groove 7 at the bottom of the upper mold 2. The top two sides of the cavity block 6 have the same structure as the bottom two sides of the core block 5.

[0018] Specifically, a torsion spring 17 is sleeved on the outer periphery of one end of the rotating shaft 16, and the two ends of the torsion spring 17 are fixedly connected to the gear 15 and the inner wall of the core block 5 or the cavity block 6, respectively.

[0019] Specifically, guide rods 19 are fixedly welded to the bottom of the core block 5 and the top of the cavity block 6. Guide grooves 9 are opened on the bottom surface and top wall of the mounting groove 7, and the guide rods 19 are inserted into the guide grooves 9.

[0022] In this embodiment, during use, when it is necessary to disassemble and replace the core block 5 and the cavity block 6, after separating the lower mold 1 from the upper mold 2, the L-shaped lever 11 in the rectangular grooves 10 on both sides of the core block 5 and the cavity block 6 is moved, causing the straight rod 12 to move. This causes the corresponding locking block 13 to retract into the core block 5 or the cavity block 6. At the same time, the toothed groove 14 on the straight rod 12 drives the gear 15 to rotate, causing the gear 15 to rotate around the rotating shaft 16 and drive the torsion spring 17 to twist. This causes the Z-shaped rod 18, which is meshed with the upper part of the gear 15, to move and retract into the core block 5 or the cavity block 6, causing the locking block 13 at its end to retract synchronously. This achieves the purpose of releasing the jamming state. Then, the core block 5 and cavity block 6 are removed, and the new core block 5 and cavity block 6 are installed into the corresponding mounting slots 7 after the above operation. This enables quick assembly and disassembly of the core block 5 and cavity block 6. This design greatly improves the convenience of assembling and disassembling the core block 5 and cavity block 6. During the assembly and disassembly process, the guide groove 9 set in the mounting slot 7, together with the guide rod 19 set at the bottom of the core block 5 and the top of the cavity block 6, guides and limits the core block 5 and cavity block 6. This improves the stability of the core block 5 and cavity block 6 after installation and avoids displacement, which could lead to deviations during mold closing and affect the processing hardness.
